A Grand Prairie man has been arrested in connection with an alleged hit-and-run crash that killed a highway construction worker on the President George Bush Turnpike Monday morning.

Investigators said a construction convoy that consisted of a large truck with a large blinking arrow and a pickup truck carrying a trailer was going at a very slow speed in the shoulder. There was one construction worker riding in the trailer putting reflective markers in the road.

Police said Francisco Castillo, 24, of Grand Prairie, was driving a Chevrolet Impala when he approached the convoy and went around the first truck, but then hit the truck with the trailers.

The construction worker riding in the trailer was killed instantly. The Dallas County Medical Examiner's Office identified the worker as 41-year-old Camerino Sixtos.

The driver of the pickup suffered non life-threatening injuries.

After the impact with the truck and trailer, the Impala went across three lanes of traffic and hit another construction vehicle, police said.

Castillo and another person left the crash scene in another vehicle that was not involved in the crash, police said.

Castillo was treated at an area hospital for injuries from the crash and released, then booked into the Dallas County Jail on two counts of felony fail to stop and render aid, police said. Online jail records don't list an attorney for Castillo.

"With this one you are looking at a felony, fail to stop and render aid, you have someone with seriously bodily injury or death, and in this case we have a fatality, so they are looking at felony charges," Haschel said.
